FEDERAL WAY, Wash. -- California's Thomas Shields won the 100-yard butterfly and the 100 backstroke Friday night to help the defending champion Golden Bears stretch their lead in the team standings at the NCAA men's swimming and diving championships.

Cal finished the middle day of the three-day meet with 379.5 points. Texas was second heading into Saturday's final day with 343.5.

Shields, a junior, won the butterfly in 44.76 seconds, then took the backstroke in 44.86.

Arizona freshman Kevin Cordes set a new American record in the 100 breaststroke with a 51.32 during the preliminaries, then came back and won the title in the evening with a 51.71. The previous record was 51.35 by Michael Alexandrov in December 2010.

Cordes also was part of the Arizona 200 medley relay team that set an American record of 1:23.53.
